This is the perfect race for night owls and stargazers alike. Beginning at sunset on Friday, July 11 and finishing just after sunrise the following day, this 12-hour solo or relay race covers a 10.3-mile loop along the rolling hills of the Highlands Ranch Backcountry Wilderness area. The course will be illuminated by the full moon, depending on the weather, and course markers include flags, reflective tape and glowsticks.
